A: To improve the compressor's displacement (gas volume) is to increase the output coefficient, usually using the following methods:

1. Correctly select the size of the clearance volume;

2, to maintain the tightness of the piston ring;

3, to maintain the tightness of gas cutting and stuffing boxes;

4, to maintain the sensitivity of suction generation and exhaust cutting;

5, reduce the resistance of gas suction;

6, should draw in relatively dry and cold gas;

7. Maintain the tightness of output lines, gas cutting, gas tanks, and coolers;

8, properly increase the speed of the compressor;

9, using advanced cooling system;

10. When necessary, clean the cylinder and other parts.
